Abstract
The known C-13 NMR spectral data of triterpenoid sapogenins and saponi ns was conveniently applied for direct structure identification of mix tures containing 28-O-beta-D-glucopyranosyl-ester-oleanolic acid and 2 8-O-beta-D-glucopyranosyl-ester-olean-9(11), 12-diene, 3-O-beta-D-gluc opyranosyl-erythrodiol and 3-O-beta-D-glucopyranosyl-11, 12-epoxy-olea n-28, 13-olide, the latter compound and 3-O-beta-D-glucopyranosyl-olea n-28, 13-olide from Gomphrena macrocephala.
